* WHAT…Large breaking waves of 18 to 22 feet expected in the
surf zone.
* WHERE…North Coast and Central Coast zones.
* WHEN…From 5 AM early this morning to 9 PM PST this evening.
* IMPACTS…Large waves may wash over beaches, jetties, and other
structures unexpectedly. Localized beach erosion is possible.
People can be swept off rocks and jetties, and drown while
observing high surf.
* ADDITIONAL DETAILS…Waves just offshore on Monday morning are
expected to be of a longer period with a dominant period of 20
to 22 seconds. This may enhance the risk for beach erosion and
infrastructure damage on west or southwest facing beaches.
